Any tips on why I am getting overflow errors any time I try to load an impulse file in the automatic EQ block?

The DSP is ADAU1452. The file was recorded at 48KHz and exported from ARTA as an MLSSA ASCII file.

Hi there,

Could you please check your text file once. The MLSSA file should match the format given in the wiki page below

Speaker Response: MLSSA [Analog Devices Wiki]

And we also recommend you to use frequency response instead of impulse response and then the values you have mentioned are huge.The processor might be expecting a decimal value.

Kindly do check once and revert us.

Regards,

Harish

Thanks for the link. I exported frequency response and phase rather than impulse. Then I had to change the header info as per the link. Works now!

I've asked the author of Room EQ Wizard if he can add a export option that directly works with Sigma Studio.
